  21. Unit 6Indices and Factors Factors

  22. A factor of a positive whole number is any positive whole number that will divide exactly into it. Example: Find all the factors of 20 You can write 20 as: So factors of 20 in increasing order are: 1 2 4 5 10 20

  24. Unit 6Indices and Factors Prime Factors

  25. Any positive whole number can be written uniquely as the product of its prime factors. Example: Write the number 276 as a product of its prime factor This is unique ? ? ?

  27. Unit 6Indices and Factors HCF and LCM

  28. The HCF (Highest Common Factor) of two (or more) positive integers is the largest number which is a factor of both (or all) the numbers. Example: Find the HCF of 120 and 105 So, HCF = 3 x 5 = 15 Check: ,

  29. The LCM (Lowest Common Multiple) of two (or more) positive integers in the lowest number into which both (or all) of the numbers can divide exactly. Example: Find the LCM of 24 and 60 Multiples of 24 are: Multiples of 60 are: So LCM = 120 Check , 24, 48, 72, 96, 120, 144, . . . 60, 120, 180, 240, 300, . . .
